INVENTOR ATTORNEY UNITED STATES CHARLES J. HENSCHEL, OF BROOKLYN, NEW YORK.

' SHIP S TELEGRAPH.

- Application filed April 4,

To all whom it may concern:

Be it known that 1, CHARLES J. HENSGHEL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Ships Telegraphs, of which the following is a full, clear, and concise description.

y invention relates to ships telegraphs, that is, to signaling devices used upon shipboard for enabling an officer located for the time being upon one part of the vessel to transmit certain conventional signals to another officer or attendant located upon a different part of the vessel, and to receive from him an afiirmative indication that the signal is understood.

More particularly stated, my invention relates to the type of ships telegraph which as usually built comprises two instruments known respectively in this art as a transmitter and receiver, yet each having to some extent at least the functions of both a transmitter and a receiver, the two instruments being connected together by means of flexible connections of great length extending between them, the energy required for transinission being furnished altogether by the muscular efforts of the respective operators.

The main purpose of my invention is to provide two instruments with a single set of flexible connections extending therebetween and common thereto, the various parts being so adapted and arranged that this set of flexible connections may be at one moment under control of the one instrument and at a different moment under control of theother instrument, and while under control of one instrument being incapable of causing that instrument to register an indication, but capable of causing the other instru ment to register an indication.-

A further purpose of my invention is to prevent confusion in the transmission and reception of signals, by so forming and arranging the parts that the operator at the transmitting station must finish his signal and lock his instrument before the operator at the receiving station can effectively make any response.

.-y invention also comprehends general improvements in the mechanism of the ships Specification of Letters Patent.

telegraph, for the purpose of increasing the general efiiciency thereof.

Reference is made to the accompanying drawings forming a part of this specification, and in which like reference characters indicate like parts throughout the several figures. I

Figure 1 is a front view of the transmitter and the supporting column upon which it is mounted, the transmitter except for the ad dition of the supporting column having a structure like that of the receiver.

Fig. 2 is a substantially central vertical iection through the mechanism shown in Fig. 3 is a section on the line 33 of Fig. 2, looking in the direction indicated by the arrows.

Fig. 4 is a fragmentary section corresponding to the right hand portion of Fig. 2, but showing the device as adapted for use with flexible shafting instead of with a chain drive.

Fig. 5 is a diagrammatic elevation of my system as used with a chain drive.

Fig. 6 is a diagrammatic elevation of my system as employed with a flexible shafting drive. 7

Mounted upon the topof a supporting column 7 is a casing 8, provided with aface plate 9 and serving as a housing.

The face plate is provided with legends Back, Ahead, Stop, Full, Half, Slow, the three legends last mentioned each being duplicated.

The face plate 9 is at its outer eral edge provided with notches 10, spaced equidistant and serving as sector n tches.

An arm 11, carrying a handle 12, is provided with a collar 13, secured firmly upon the adjacent end of a tubular shaft 14:. A

Extending through the tublar shaft 1% is a smaller shaft 15, provided with a swivel head 16. A swivel fork 17 engages the swivel head 16, and therewith forms a swivel joint.

A lever 18, having approximate V-form, is journaled upon the arm 11 by aid of bearings 19, and is adapted to swing slightly in relation to the arm 11, as may be understood from Fig. 2. When the lever occupies its position indicated by dotted lines, it is in its or periphnormal condition of inactivity. When it ings and 26. The bearing it is in its abnormal condition-as when the arm 11 is being moved, or at. least is unlocked and readytobe shifted. The dotted arrows in Fig. 2 indicate the direction of movement of the lever 18 as 1t returns to its normal position after each time it is.

used.

The lever 18 carries a pawl 21, the point of which is so formed and arranged as to easily slip into some one of the notches 10 and thus for the time being lock the arm 11 so as .to prevent it from being shifted.

The tubular shaft 14, extends through another tubular shaft 22, and fitted rigidly upon this tubular shaft is a disk 23, having. a portion 24 projecting radially outward and serving as a pointer. 1

The tubular shaft 22 is supported by bear- I 25 is integral with the face plate 9, and the-bearing 26 is carried by a spider 27. This spider hasthe generalform indicated in Fig. 3, and is pro vided with feet 28 secured to the casing.

Mounted rigidly upon the tubular shaft 22 is a'centeringwheel 29, provided with a number of notches 30, spaced equidistant, as shown in Figs. 2 and 3. Engaging the centering wheel is a roller 31, carried by an arm 32, and adapted to fit into the notches one at a time as the centering wheel isturned. The arm 32 is mounted upon a pin 33, and thus adapted to rock. ported by a lug 34. the pin 33 and engages the A spring 35 encircles arm 32 so as to press it against the centering wheel 29.

The centering wheel performs two ofiices. First, it enables the operator to stop the The arm 32 carries clapper 36 is a gong arm 11 in certain definite and exact posi tions, corresponding to and indicated by the legends displayed by the face plate. Second,

Mounted within these two bearings 41,42, and supported thereby, is a shaft 43. Encircling' this shaft 43, and

slidahle relatively thereto, is a sleeve 44, carrying a gear wheel and swivel head 46. The sleeve 44 engages a spline key 47 which extends through it and is carried by the shaft 43.

' "A sprocket wheel 48 is mounted rigidly upon the shaft 43, and carries a sprocket chain 49.

. A forked lever 50 is journaled to rock on: a p1n'51, and 18 provided with a slot '52,-

The .pin 33 is supwheel 59, these two gear wheels each having the same number of teeth, which are beveled; The two gear wheels also have each the same diameter. 7

Each time the lever 18:is rocked relatively to the arm 11, as indicated by dotted lines in Fig. 2 and as above described, the small shaft 15 is moved endwise relatively to the tubular bearing 14, through which it extends. As a consequence, the fork 50 is rocked upon the pin 51, so that the sleeve 44 is moved a little distance along the shaft 43. The gear wheel 45 moves'out of mesh with the gear wheel 58 and into mesh with the gear wheel 59 each time the lever 18 swings from its position indicated by full lines to that indicated by dotted lines in Fig. 2. This movementis under impulse of the spring 57. Eachytime the lever 18 is moved into the position indicated'in Fig. 2 by full lines however, the gear wheel 45 moves out of mesh with the gear wheel 59 and into mesh with the gear wheel 58.

Thus with the handle 20 pressed toward the handle 12 as shown in Fig. 2, if the arm 11 be rocked, the gear wheel 58 must cause the gear wheel 45' to turn and to drive the shaft 43 with its sprocket 48.: Yet with the handle 20. moved away from the handle 12,

the pawl 21 thus entering one of the notches- Both the collar and a number of guide pulleys 62, as may beunderstood from Fig. 4.

Fig. 4 shows the-transmitter and receiver with the chain extending therebetween; The transmitter is at the left of the figure, the receiver appearing at the right. As a matter of convenience the parts of the receiver corresponding to the parts 10, 18, 20, and 24 of the transmitter are designated as 10 18 20 and 24% A movement communicated to the chain by means of thetransmitter mechanism isreadily transmitted to the receiver, and there communicated to such movable parts as may for the moment be under control of the chain. Similarly a movement communicated to the chain by the receiver mechanism is readily communicated to such movable parts, within the transmitting mechanism, as may now be under control of the chain.

Referring more particularly to Fig. 2, it will be noted that when the lever 18 is pressed toward the arm 11 as shown by full lines, and the arm 11 is then rocked as elsewhere described, the gear wheel 58 turns the gear wheel 45 sothat the chain 49 is driven by movements of the arm 11, while the gear wheel 59 is idle and the pointer 74 is for the time being motionless. When, however, the arm 11 occupies its normal position indicated by dottedlines, so that the arm 11 is locked by the pawl 21 and the disengagement of the gear Wheel 45 from the gear wheel 58 frees the chain 49, any movement conferred upon the chain from the receiving station must turn the sprocket Wheel 48, shaft 43 and gear wheels 45 and 59, and hence the pointer 24 is turned accordingly.

Thus the operator at the transmitting stae tion can register an indication at the receiving station but not at the transmitting station, and the operator at the receiving station can register an indication at the transmitting station but not at the receiving station. i

Only one operator can use the apparatus at a time. As a result the operator at the receiving station is unable to answer any signal until the latter is finished and the operator at the transmitting station has locked the arm 11.

Instead of the chain 49, I sometimes use a line of shafting, as shown in Figs. 5 and 6. This line of shafting contains shaft sections 63, 63*, 63 bevel gears 63, a universal joint 68 and an extensible coupling 63 The line of shafting is therefore essentially a flexible shaft. I

In order to adapt my apparatus for use with a flexible shaft, I find it convenient to use at each of the two stations the arrangement shown in Fig. 6'.

The shaft section 63 extends through bearings 64, 65, carried by hangers 66, 67, the same extending from a spider 68 and the latter having feet 69 which are secured to the casing. The spider 68 is provided with a bearing 7().having the form of a sleeve, and through which the shaft'43 extends. This shaft carries a bevel gear 71, which meshes with a bevel gear 72 carried by the shaft section 63. A set collar 73 rests upon the bearing and sustains the end thrust of the shaft section 63.

The other parts shown in Fig. 6 are as to structure and action identical with those already described in connection with Fig. 2.

The operation of my device is as follows:

The various parts being assembled and arranged as shown in the drawing and as above described, the device is ready for use.

Suppose the apparatus is in the condition indicated in Fig. 4 or in Fig. 5, and that the operator at the transmitting station? wishes to transmit the signal indicatedbv the legends Back and Slow. He grasps the handle 12 (see Fig. 2) and with it the handle 20, thus rocking the lever 18 slightly in a clockwise direction according to Fig. 2, as above described. This moves the pawl 21 out of engagement with the face plate 9 and leaves the arm 11 free. The operator then rocks this arm slightly in a contra-clockwise direction according to Fig. 4, so that the legend Slow is displayed through the V- shaped arm 18, the handle 20 being released and the pointof the pawl being allowed to enter the proper notch 10. This locks the arm 18.

The movement just described for the arm 18 causes the gear wheel 45 to move out of engagen'ient with the gear wheel 59, into engagement with the gear wheel 58 and then back into engagement with the gear wheel 59. The movement of the arm ll, taking place as it does while the gear wheel 45 momentarily in engagement with the gear wheel 58 and out of engagement with the gear wheel 59, causes the wheel 4:) to turn the shaft 43 and move the chain or flexible shaft, but has no effect whatever upon the tubular shaft 22 or the pointer 24 at the transmitting station.

At the receiving station, however, the situation is different, the lever 18 remaining stationary and the pointer 24 moving in response to the signal thus transmitted.

T he operator at the receiving station, hearing his gong sounded, glances at the receiver and notes the signal as indicated by the pointer. As soon as the pointer stops moving, he answers by merely repeating the signal, which causes the pointer 24 at the transmitting station to move to the position associated with the signal in question. The gong at the transmitting station is of course. sounded along with the movement of the pointer, and the operator at the transmitting station is apprised that his signal is under stood, and just how it is understood.

The ships telegraph now remains undis turbed until'another signal is to be transmitted, whereupon the cycle of operations is repeated.

I do not limit myself to the particular mechanism shown, as variations may be made'therefrom without departing from my invention, which is commensurate with my claims.

I claim:

1. In a ships telegraph the combination of a set of flexible connections extending from one station to another and movable from each of said, stations for the purpose of transmitting signals, an actuating device at each station for moving said set of flexible connections in order to transmit a signal, an indicating member at each station to be actuated by said set or' flexible connections in order to receive a signal and mechanism located at each station and controllable at the will of the operator for connecting said set of flexible connections with either said actuating device or said indicating device at the will or the operator and of locking said actuating device in order to render'it inactive while said set of flexible connections is connected with said indicating member.
